But the measurement is tricky, and researchers had hoped that
studying radio wavelengths would give a more precise result.
Thus, the team set out to
study radio wavelengths.

It will snap the first close - up images of Pluto and Charon, map their surface features with visible -
wavelength cameras,
study their compositions in the near - infrared spectrum, and monitor Pluto's thin atmosphere with ultraviolet spectrometers and
radio waves.
ALMA will consist of 64 12 - meter - diameter dish antennas comprising a single imaging telescope to
study the universe at millimeter and submillimeter
wavelengths — the region between
radio waves and infrared waves.
Ongoing
radio observations (SMA, JCMT, VLA) of Sirius A are being used to set an observationally determined standard for stellar atmosphere modeling and debris disk
studies around A stars, as well as to take the first step toward characterizing potential intrinsic uncertainty in stellar emission at these
wavelengths.
Operating at a
wavelength of 2 centimetres, it was used to
study galactic and extragalactic objects that emit
radio waves, such as quasars.
«Young pulsars are particularly rare, and being able to
study such a young one at
radio wavelengths provides an outstanding opportunity to learn critical facts about their evolution and workings.»
The New Worlds Technology Development Program, which lays the scientific groundwork for a future mission to
study nearby Earth - like planets, and the Cerro Chajnantor Atacama Telescope, which would provide short -
wavelength radio surveys to
study dusty material associated with galaxies and stars, are ranked the highest priority for midsize space - and ground - based programs, respectively.
What is unique is that at the dawn of
radio astronomy, a scientist predicted hydrogen would emit this radiation at detectable
radio wavelengths, and this prediction offered astronomers a new tool for
studying the universe.
After
studying VLA and Keck data on 26 galaxies and quasars, Wardle, Perley and Cohen conclude that «the observational data at both optical and
radio wavelengths show that any rotation of the plane of polarizaton over cosmological distances is unmeasurably small and is indistinguishable from zero.»
But in order to understand the universe, we need to
study astronomical objects over the broad range of
wavelengths they emit — from the gamma rays emitted from emerging stars to the
radio waves released from black holes.
